Indian Mobility Given Peasant Migrations The Bari Indians of the northern Colombian forests are semi-nomads. For the past 30 years, they have had to deal with the colonization of their territory by peasants who, in pursuit of survival strategies, are looking for new land. These Indians have been gradually forced to restrict their mobility. The social dynamics of Bari acculturation are analyzed in terms of the effects that modified social relations have on practices related to the use of space. Despite an apparent convergence of their farming systems and ways of life, the situations experienced by the Bari and by colonists have neither the same contents nor the same social meaning.
